Harvested Notty & S-05 ? wow.
 
Good points. All methods are viable and have advantages/disadvantages. I don't suggest that one is better than another, although, I believe that frozen (in the correct manner) would probably last the longest. My purpose with the post was simply to provide some information regarding suggested shelf lives of different methods as an answer to the question posed by hollywoodbrew. In a world of conflicting information regarding yeast propogation, the Maltose Falcon article is, IMO, one of the most reliable.

Do you have a link to that TBN podcast on yeast? I'd love to listen to that. Any other info on this topic that you can point me to that you feel is worth while?
The article is great, however since we can reculture from (virtually) one viable cell, many storage methods are much the same in terms of being viable after years. However, preventing yeast mutation (which is not really mentioned in that article) is possibly more important than the viability after long term storage. I have a non-frost-free-freezer, so have just started freezing samples, hopefully to keep them more pristine, and also because slants get tedious the more yeast you get - maybe I'll update this in 5 years when I know more about the viability/mutation over time. ;)

I am also planning an adding the Koelsch II to my library. Harvesting Notty makes sense since they have had some quality control issues in the recent past (I still have several satchels with holes in them lying around) - otherwise, it's too cheap to save money when figuring in the DME cost for the starter. I switched from harvested US-05 to 001 for my American Ale strain, since the liquid yeast is supposedly slightly cleaner.
